A 144V 520Ah LiFePO4 traction pack for golf carts and low-speed electric vehicles that run all day and charge overnight. Nominal energy is approximately 74.88 kWh (calculated from nominal voltage and rated capacity; delivered usable energy depends on discharge current, operating temperature, cutoff voltage, and application duty cycle). The pack delivers 300A continuous discharge current, with peak discharge capability up to 450A (30s pulse duration, subject to thermal and BMS limits), rated at a 0.58C rating suited to mixed duty: sustained running with periodic higher demand.
Charging at 100A brings it to full in roughly 6 hours. The operating window is -20~75°C on discharge and 0~45°C on charge. The pack measures 1500 x 360x 300 mm / 1500 x 640x 300 mm and weighs 660 kg.
Nothing here is fixed. Capacity, box dimensions, terminals and cable exit are drawn to the cart. CAN and RS485 handle controller integration and Bluetooth covers day-to-day checks. Where a fleet genuinely needs remote visibility across dozens of vehicles, WiFi or 4G telemetry is available as a custom option.
What if we need a different capacity?
Capacity is a design input. Tell us the runtime you need and the cart’s average and peak draw and we size to it.
How do you handle fleet rollouts?
Pilot pack first, then production once the duty cycle is confirmed in the field. It is cheaper than discovering a sizing error across forty carts.
Grade A prismatic LFP cells, generally specified with UL recognition at cell level. Every pack ships with a UN38.3 test summary and MSDS prepared for air, sea and road transport. Assembly and testing take around 7 working days. Cell supply is what sets the overall schedule: when the cells your design needs are in stock, samples ship in 12–15 working days; when they have to be sourced, allow 20–25. Tell us your target date early and we will confirm cell availability before you commit to it. Production runs 30–35 working days. There is no minimum order quantity — this is a custom design business and we quote single units, with pricing improving noticeably from 100 packs upward. LiFePO4 warranty typically runs 3–5 years, set against the discharge duty of the application; high-rate cycling shortens it.
Our engineering division designs bespoke battery packs with CANBUS, RS485, custom aluminum enclosures, and matched chargers.
